Identify the value of a if
y= ax+ 7x + 2
and the point (2, 12) is on the graph.
Answer:
a=-2
So yep. ;)
Step-by-step explanation:
Alright, so, (2,12), 2 is the x and 12 is the y.
Stick them into the equation: [tex]12=a*2+(7*2)+2[/tex]
Then, solve:
[tex]12=a*2+14+2[/tex]
a = -2
So yes, they're on the graph.
Hope this helped! :)

Step-by-step explanation:
find the measure of
a. 71 degrees
b. 109 degrees
c. 180 degrees
d. 82 degrees
Answer:
71°
Step-by-step explanation:
Given;
<A=27°
<B=82°
<T=?
We add all angles and subtract it from 180 since an interior angle adds up to 180
<A+<B+<T=180
27°+82°+<T=180
109°+<T=180
<T=180-109
<T=71°
Therefore angle T <T is equal to 71°degrees

how to find the circumferenceof a circle
Answer:
You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that point.
Step-by-step explanation:
Answer:
C=2[tex]\pi[/tex]r
Step-by-step explanation:
To find the circumference of a circle you have to use the formula:
c= 2 [tex]\pi[/tex] r
c being circumference
r being radius
If your given diameter than divide that by 2 to get radius
[In case you need it in the future]
To find area of a circle use the formula:
A = [tex]\pi[/tex] r^2
A being area
r being radius

Eight more than the product of a number and 3 equals 9.
Answer:
3n + 8 = 9
Step-by-step explanation:
"eight more" represents adding 8, so +8
"product of a number and 3" represents multiplying n by 3, so 3n
"equals 9" means that 3n + 8 = 9
Answer:
n = 1/3
Step-by-step explanation:
n = a number
8 + 3n = 9
3n = 1
n = 1/3

4u+3u+21=70 find the value of the variables
Answer:
u=7
Step-by-step explanation:
First, add 4u and 3u because they are like terms.
7u+21=70
Second, subtract 21 from both sides.
7u=49
Finally, to isolate the variable divide 7 from both sides.
u=7
if the volume if a cylindrical solid is 1320 and base area is 264 . find its height
Answer:

Mary and Darryl are selling flower bulbs for a school fundraiser. Customers can buy bags of
windflower bulbs and bags of daffodil bulbs. Mary sold 10 bags of windflower bulbs and 4
bags of daffodil bulbs for a total of $226. Darryl sold 6 bags of windflower bulbs and 4 bags of
daffodil bulbs for a total of $166. What is the cost each of one bag of windflower bulbs and
one bag of daffodil bulbs?
Answer:
15 windflower bulbs
19 daffodil bulbs
Step-by-step explanation:
Given
Represent windflower with W and daffodil with D.
So:
Mary's sales is:
10W + 4D = 226 --- (1)
Darryl's sales is:
6W + 4D = 166 ---- (2)
Required
Solve for W and D
We'll make use of elimination method.
Start by subtracting (2) from (1)
10W - 6W + 4D - 4D = 226 - 166
4W = 60
Multiply both sides by ¼
¼ * 4W = 60 * ¼
W = 60 * ¼
W = 15
Substitute 15 for W in (1)
10W + 4D = 226
10 * 15 + 4D = 226
150 + 4D = 226
Collect like terms
4D = 226 - 150
4D = 76
Multiply both sides by ¼.
¼ * 4D = 76 * ¼.
D = 19
Tobias Gold sells computers at The Office Center.
He is guaranteed a minimum salary of $1,959 per month plus
6.3% commission on total sales. How much in total sales does
he need in order to have a gross pay for the month of $2,784.84?
Answer:
Total sales to be made = $13108.57
Step-by-step explanation:
Given that:
Monthly salary = $1959
Commission = 6.3%
Monthly pay to be earned = $2784.84
Commission amount = 2784.84 - 1959 = $825.84
Let,
x be the amount of sales
6.3% of x = 825.84
[tex]\frac{6.3}{100}x=825.84\\0.063x=825.84[/tex]
Dividing both sides by 0.063
[tex]\frac{0.063x}{0.063}=\frac{825.84}{0.063}\\x=13108.57[/tex]
Hence,
Total sales to be made = $13108.57

A florist is looking to make arrangements of red and white roses for bouquets. The flowers are priced so that she makes a profit of $1.25 per red rose and $1.00 per white rose in a bouquet. Her goal is to make at least $1000 from sales of these bouquets. Based on her available time and supplies of red and white roses, she is considering two possibilities: 130 bouquets of 4 red roses and 3 white roses each or 110 bouquets of 3 red roses and 5 white roses each. Will either of these possibilities turn the profit the florist is seeking?
Answer:
Option 1Step-by-step explanation:
Option 1
130 bouquets of 4 red roses and 3 white roses each. Profit is:
130*(4*$1.25 + 3*$1) = $1040 > $1000Option 2
110 bouquets of 3 red roses and 5 white roses each. Profit is:
110*(3*$1.25 + 5*$1) = $962.50 < $1000As we see option 1 is bringing target profit so should be her choice
Answer:
30 bouquets of 4 red roses and 3 white roses each.

solve 3(6b-1)-7(2b+3)=0
Answer:
24/13 or 1.8
Step-by-step explanation:
27b -3 - 14b -21 = 0
13b - 24 = 0
13b = 24
b = 24/13 or 1.8
Answer:
B = 6
Step-by-step explanation
1. (Do the parentheses) 3(6b-1)-7(2b+3) = 18b-3-14b-21
2. (Simplify) 18b-3-14b-21 = 4b-24
3. (Add 24 to both sides) 4b-24+24=0+24
4. (Simplify) 4b = 24
5. (Divide by 4) b = 6
